2 SAFETY PRECAUTIONS - English

WARNING: These Safety Precautions are for your protection. They summarize precautionary

information from the references listed in Additional Safety Information section. Before performing any

installation or operating procedures, be sure to read and follow the safety precautions listed below as

well as all other manuals, material safety data sheets, labels, etc. Failure to observe Safety

Precautions can result in injury or death.

PROTECT YOURSELF AND OTHERS

Some welding, cutting and gouging precesses are noisy and require ear

protection. The arc, like the sun, emits ultraviolet (UV) and other radiation

and can injure skin and eyes. Hot metal can cause burns. Training in the

proper use of the processes and equipment is essential to prevent accidents.

Therefore:

1. Always wear safety glasses with side shields in any work area, even if welding helmets face

shields and goggles are also required.

2. Use a face shield fitted with the correct filter and cover plates to protect your eyes, face, neck

and ears from sparks and rays of the arc when operating or observing operations. Warn

bystanders not to watch the arc and not to expose themselves to the rays of the electric-arc or

hot metal.

3. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt, cuffless trousers, high-topped

shoes and a welding helmet or cap for protection, to protect against arc rays and hot sparks or

hot metal. A flameproof apron may also be desirable as protection against radiated heat and

sparks.

- 5 -

US warnings

4. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves and collars

should be kept buttoned and open pockets eliminated from the front of clothing.

5. Protect other personnel from arc rays and hot sparks with a suitable nonflammable partition or

curtains.

6. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be hot and

can fly far. Bystanders should also wear goggles over safety glasses.

FIRES AND EXPLOSIONS

Heat from flames and arcs can start fires. Hot slag or sparks can also cause

fires and explosions. Therefore:

1. Remove all combustible materials well away from the work area or cover the materials with a

protective nonflammable covering. Combusible materials include wood, clot, sawdust, liquid and

gas fuels, solvents, pants and coatings papper, etc.

2. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings and cause a

hidden smoldering fire or fires on the floor below. Make certain that such openings are protected

from hot sparks and metal.

3. Do not weld, cut or perform other hot work until the workpiece has been completely cleaned so

that there are no substances on the workpiece which might produce flammable or toxic vapors.

Do not do hot work on closed containers. They may explode.

4. Have fire extinguishing equipment handy for instant use, such as a garden hose, water pail, sand

bucket, or portable fire extinguisher. Be sure you are trained in its use.

5. Do not use equipment beyond its ratings. For example, overloaded welding cable can overheat

and create a fire hazard.

6. After completing operations, inspect the work area to make certain there are no hot sparks or hot

metal which could cause a later fire. Use fire watchers when necessary.

7. For additional information refer to NFPA Standard 51B, “Fire Prevention in Use of Cutting and

Welding Processes”, available from the National Fire Protection Association, Batterymarch Park,

Quincy, MA 02269.

ELECTRICAL SHOCK

Contact with live electrical parts and ground can cause severe injury or

death. DO NOT use AC welding current in damp areas, if movement is

confined, or if there is danger of falling. Therefore:

1. Be sure the power source frame (chassis) is connected to the ground system of the input power.

2. Connect the workpiece to a good electrical ground.

3. Connect the work cable to the workpiece. A poor or missing connection can expose you or others

to a fatal shock.

4. Use well-maintained equipment. Replace worn or damaged cables.

5. Keep everything dry, including clothing, work area, cables, torch/electrode holder and power

source.

6. Make sure that all parts of your bady are insulated from work and from ground.

7. Do not stand directly on metal or the earth while working in tight quarters or a damp area; stand

on dry boards or an insulating platform and wear rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the power.

9. Turn off the power before removing your gloves.

10. Refer to ANSI/ASC Standard Z49.1 (listed on next page) for specific grounding

recommendations. Do not mistake the work lead for a ground cable.

- 6 -

US warnings

ELECTRIC AND MAGNETIC FIELDS

May be dangerous. Electric current flowing through any conductor causes

localized Electric and Magnetic Fields (EMF). Welding and cutting current

creates EMF around welding cables and welding machines.

Therefore:

1. Welders having pacemakers should consult their physician before welding. EMF may interfere

with some pacemakers.

2. Exposure to EMF may have other health effects which are unknown.

3. Welders should use the following procedures to minimize exposure to EMF:

a. Route the electrode and work cables together. Secure them with tape when possible.

b. Never coil the torch or work cable around your body.

c. Do not place your body between the torch and work cables. Route cables on the same side

of your body.

d. Connect the work cable to the workpiece as close as possible to the area being welded.

e. Keep welding power source and cables as far away from your body as possible.

FUMES AND GASES

Fumes and gases, can cause discomfort or harm, particularly in confined

spaces. Do not breathe fumes and gases. Shielding gases can cause

asphyxiation.

Therfore:

1. Always provide adequate ventilation in the work area by natural or mechanical means. Do not

weld, cut or gouge on materials such as galvanized steel, stainless steel, cooper, zinc, lead

beryllium or cadmium unless positive mechanical ventilation is provided. Do not breathe fumes

from these materials.

2. Do not operate near degreasing and spraying operations. The heat or arc can react with

chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas and other irritant gases.

3. If you develop momentary eye, nose or throat irritation while operating, this is an indication that

ventilation is not adequate. Stop work and take necessary steps to improve ventilation in the work

area. Do not continue to operate if physical discomfort persists.

4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for specific ventilation recommendations.

5. WARNING: This product when used for welding or cutting, produces fumes or gases which

contain chemicals known to the State of Californa to cause birth defects and in some cases

cancer (California Health & Safety Code §25249.5 et seq.)

CYLINDER HANDLING

Cylinders, if mishandled, can rupture and violently release gas. Sudden

rupture of cylinder valve or relief device can injure or kill.

Therefore:

1. Use the proper gas for the process and use the proper pressure reducing regulator designed to

operate from the compressed gas cylinder. Do not use adaptors. Maintain hoses and fittings in

good condition. Follow manufacturer's operating instructions for mounting regulator to a

compressed gas cylinder.

2. Always secure cylinders in an upright position by chain or strap to suitable hand trucks,

undercarriages, benches, wall, post or racks. Never secure cylinders to work tables or fixtures

where they may become part of an electrical circuit.

3. When not in use, keep cylinder valves closed. Have valve protection cap in place if regulator is

not connected. Secure and move cylinders by using suitable hand trucks.

4. Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.

5. For additional information, refer to CGA Standard P-1, “Precations for Safe Handling of

Comporessed Gases in Cylinders”, which is available from Compressed Gas Association, 1235

Jefferson Davis Highway, Arlington, VA 22202.

EQUIPMENT MAINTENANCE

Faulty or improperly maintained equipment can cause injury or death. Therefore:

1. Always have qualified personnel perform the installaion, troubleshooting and maintenance work.

Do not perform any electrical work unless you are qualified to perform such work.

2. Before performing any maintenance work inside a power source, disconnect the power source

from the incoming electrical power.

3. Maintain cables, grounding wire, connections, power cord and power supply in safe working

order. Do not operate any equipment in faulty condition.

4. Do not abuse any equipment or accessories. Keep equipment away from heat sources such as

furnaces, wet conditions such as water puddles, oil or grease, corrosive atmospheres and

* ELP = ESAB Logic Pump, see point 9.2.

Make sure the torch chosen is of the proper rating for the welding current to be

used, has the proper size and type of liner, the proper contact tip and the proper

guide tube.

9.2 Water connection

When connecting a water-cooled welding gun, the power source's main power

supply switch must be in the Off position and the cooling unit switch must be in

position “ELP/0”.

The wire feed unit with water connection is equipped with a detection system ELP

(ESAB Logic Pump) which checks that the water hoses are connected. When

connecting a water-cooled welding gun, the water pump starts.

Detection only works with power sources that are equipped with ELP.

- 24 -

bm33d1aa

9.3 Starting procedure

When the wire feed starts, the power source generates welding voltage.

If there is no welding current flow within three seconds, the power source switches the

welding voltage off. The wire feed continues until the welding gun's switch is switched

off.

9.4 Function explanations

Burnback time

Burnback time is a delay between the time when the wire starts to brake until the

time when the power source switches off the welding voltage. Too short burnback

time results in a long wire stickout after completion of welding, with a risk of the wire

being caught in the solidifying weld pool. Too long a burnback time results in a

shorter stickout, with increased risk of the arc striking back to the contact tip.

Slow run in

Slow run in start means that the wire is fed at low speed until it comes into electrical

contact with the workpiece and then the speed increases to the set speed.

2 stroke

With 2 stroke, the gas flow and wire feed start when the trigger switch is pressed in

and end when it is released.

4 stroke

With 4 stroke, the gas flow starts when the trigger switch is pressed in and the wire

feed starts when it is released. The welding process continues until the switch is

pressed in again, the wire feed stops and when the switch is released the gas stops

flowing.

Wire feed speed

This sets the required feed speed of the filler wire in m/minute.

- 25 -

bm33d1aa

9.5 Wire feed pressure

Start by making sure that the wire moves smoothly through the wire guide. Then

set the pressure of the wire feeder's pressure rollers. It is important that the

pressure is not too great.

Fig 1 Fig 2

To check that the feed pressure is set correctly, you can feed out the wire against

an insolated object, e.g. a piece of wood.

When you hold the gun approx. 0.2” (5 mm) from the piece of wood (fig. 1) the

feed rollers should slip.

If you hold the gun approx. 2” (50 mm) from the piece of wood, the wire should be

fed out and bend (fig. 2).

WHEN THE WIRE FEEDER IS CONNECTED TO THE POWER SOURCE, THE WORK

LEAD FROM THE POWER SOURCE IS CONNECTED TO THE WORK PIECE AND

THE POWER SOURCE IS ENERGICED, CLOSING THE TORCH TRIGGER WILL

CAUSE THE WELDING WIRE TO BECOME ELECTRICALLY HOT AND WILL CAUSE

THE DRIVE ROLLS TO TURN. KEEP FINGERS CLEAR!

Before threading welding wire, make sure the chisel point and burrs have been

removed from the end of the wire to prevent the wire from jamming in the torch

liner.
